BOTTLE.

Specification of Letters Patent.

Patented J'uly 3, 1906.

Application filed April 18, 1905. Serial No. 256.185-

ing at Harrisburg, in the county of Dauphin and State of Pennsylvania, have invented a new and useful Bottle, of which the following is a specification.

This invention relates to bottles of that class which cannot be refilled without detection, and has for its principal object to provide a bottle of simple construction in which an air-vent is valved to prevent the passage of any liquid.

A further object of the invention is to provide a novel form of bottle in which the airvent is provided with an automaticallyclos ing valve, preferably formed of a yieldable material.

A still further object of the invention is to rovide a bottle in which the neck portion is provided with an automatically-closing valve to prevent the return of liquid to the bottle and of such construction that if any attempt is made to refill the bottle by forcing liquid under pressure thereinto the parts will be displaced in such manner that the bottle will -be rendered useless.

A still further object of the invention is to provide a construction of such character that an ordinary bottle may be employed and supplied with the attachments hereinafter described to prevent refilling.

lVith these and other objects in view, as will more fully hereinafter appear, the invention consists in certain novel features of con struction and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that various changes in the form,

proportions, size, and minor details of the structure may be made without departing from the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawings, Figure 1 is a vertical sectional view of a bottle constructed in accordance with the present invention. Fig. 2 is a similar view of the neck portion of the bottle, showing the manner in which the outlet-tube opens when liquid is being poured from the bottle. Fig. 3 is a vertical sectional view of the upper portion of the bottle, showing the manner in which the parts are displaced when an attempt is made to fill the bottle with fluid under pressure. Fig. 4 is a detail sectional view of the air-vent valve detached. Fig. 5 is a detail view of the upper air-vent valve. Fig. 6 is a detail perspective view of a modified form of bot tle-plug which may be used.

Similar numerals of reference are employed to indicate corresponding parts throughout the several figures of the drawings.

In carrying out the present invention the bottle 10 is preferably of the ordinary construction, or it may be especially made for the purpose of the invention. At the base of the neck of the bottle is arranged a cupshaped plug 12, that is preferably formed of rubber or other suitable material and held in place by its expansive tendency or by means of cement. These cups are usually formed of rubber and are of an initial diameter greater than that of the interior of the neck. They are slightly compressed and forced into place, after which in tending to reassume the original size they are firmly held against the inner wall of the neck. The base of the cup is provided with a flattened nipple 14:, over the upper end of which is stretched a pouring-tube 15, formed of a small section of fiat rubber tubing that is, tubing having an inherent tendency to flatten out or close. The entrance through the outlet-tube is preferably a trifle to one side of the center of the neck, and the tube which projects above the ring may be of any desired length, and its upper end is preferably provided with a weight or weights 16, that will cause the tube to bend over in the manner shown in Fig. 1 when the bottle is placed in a vertical position. When the bottle is turned for the purpose of pouring liquid therefrom, the stream of liquid passing through the tube will open the latter in the manner shown in Fig. 2, and when said bottle is again turned to an upright position the tube will collapse and the weighted end will fall over to the position shown in Fig. 1, and if any attempt is made to force liquid under pressure into the bottle the rubber tube as a whole will be turned and driven down to the position shown in Fig. 3, so that it will then be impossible to remove any of the contents of the bottle.

It is found in practice that when an attempt is made to refill the bottle under pressure the tube will be turned and driven to the position shown in Fig. 3 and in this position will also act as a valve. It is possible to force a quantity of liquid down through the tube while the latter is in this position; but as soon as pressure is relieved the valve closes and retains the liquid within the bottle. It is of course impossible to pour any of this liquid from the bottle through the tube, the closing of the latter effectually preventing such an operation. Aside from this the liquid and air within the bottle are confined under pressure, and if the temperature of the contents is raised even a few degrees the pressure will be increased to such an extent that the bottle will burst, and this is the invariable result of an attempt to utilize the empty bottles in this manner. It is found that the removal of a partially-refilled bottle from one room to another or the warmth of the hand in grasping the bottle is frequently sufficient to increase the pressure to the breakingpoint.

In order to prevent tampering with the pouring-tube, the upper portion of the neck of the bottle is provided with a plug 17, the periphery of which is cut away to form a number of tortuous passages 18 that will prevent the introduction of a piece of wire or other instrument, and this plug is preferably formed of glass or similar material held in place by a cement that cannot be softened or removed by any ordinary meanssuch, for instance, as a cement formed of powdered glass and ether.

The base of the cup 12 forms a support for an air-vent tube 20, said tube being preferably formed of glass and open at its upper end. The upper end of the tube 20 extends above the horizontal wall of the cup and carries a small section 21 of rubber tubing, and the upper end of the latter receives a tubesection 22, formed of glass or other rigid material, the flexible intermediate section forming a valve or closure operable by gravity when the bottle is in vertical position and opening when the bottle is turned to pour out its contents. The lower end of the tube, which is immersed in the liquid, is turned upward, and to this lower end is fitted a valve 25 of the construction best shown in Fig. 4. The lower valve is formed, preferably, of rubber or other flexible material, having an enlarged upper end 26, from which lead tubes 27 and 28, the tube 27 being placed over the upturned end of the glass tube 20, while the tube 28 is turned in traplike form and is open at 29 to permit the passage of air.

l/Vhen the bottle is in the vertical position, the upper section 22 at the top of the air-vent tube will fall by gravity, bending the intermediate section 21 and closing the vent, and at the same time the heavier upper portion 26 of the valve 25 will fall over by gravity to the position shown in Fig. 1 and effectually close the lower end of the air-vent, so that if any liquid is poured into the neck of the bottle it will not flow downward through the venttube, and, as before stated, if an attempt is made to force liquid down under pressure the pouring-tube 15 will be turned inside out and forced down into the bottle before the flexible valve 5 of the vent-tube will open. Should an attempt be made to reverse the bottle and fill under pressure, the depending tube 28 would fall over by gravity and form a closure. When the bottle is turned to a horizontal or approximately horizontal position in pourin the flexible valve will straighten out an air will flow freely therethrough to take the place of the liquid removed.

It is of course obvious that in many instances the lower valve of the air-vent may be dispensed with or the lower valve alone may be employed without departing from the invention.

In Fig. 7 is shown a slightly-modified construction of plug for preventing tampering with the outlet-tube.

The plug or disk 17 may be formed of glass or any other material and held in place by cement, springs, or other securing. means and may be provided with a passage or passages 18 of any desired character.

Having thus described the invention, What is claimed is 1. A bottle having a liquid-outlet and having an air-vent independent of said outlet, and an automatically-closable valve of flexible material for said air-vent.

2. A bottle having a liquid-outlet and having an air-vent independent of said. outlet and provided with a valve of flexible material movable automatically to closed position when the bottle is in vertical position.

3. In a bottle, an air-vent tube having a section of flexible material.

4. In a bottle, an air-vent tube formed of a plurality of tubular sections of rigid material connected by a section of flexible material.

5. In a bottle, an air-vent tube having its upper end extending into the neck of the bottle, a flexible tube-section connected thereto, and a second tube-section of rigid material secured to the upper end of the flexible section.

6. A bottle having an air-vent tube, the lower end of which is bent upward, and a flexible valve member connected to the upbent portion and having an enlarged upper end movable by gravity to prevent the passage of fluid.

7. In a bottle, a rigid air-vent tube having an. upturned end, and a flexible valve member secured thereto, said flexible valve member comprising an enlarged upper portion IIO and two tubular members, one of which is connected to the vent-tube, the other being bent upward and provided with a terminal fluid-discharge mouth.

8. In a bottle, a collapsible ouring-tube formed of thin flexible material arranged to open for the passage of a liquid during the pouring operation, and to permit reversal when subjected to pressure of fluid entering at the mouth of the bottle, said tube closing against pressure from within the bottle when in the reversed position.

9. In a bottle, a collapsible pouring-tube formed of thin flexible material arranged to close when subjected to exterior pressure, said tube being reversible when subjected to a refilling-pressure from the mouth of the bottle and acting to retain such refilling-pressure within the bottle. 7

10. In a bottle, a nipple disposed within the bottle-neck, a pouring-tube formed of a section of flexible tubing having its lower end distended over the upper portion of the nipple, forming a yieldable membrane to permit the reversal of the position of the tube when subjected to the pressure of fluid entering at the mouth of the bottle.

11. In a bottle, a cup arranged within the neck of the bottle, a nipple carried thereby, a flexible pouring-tube secured to the nipple, a vent-tube carried by the cup and having a self-closing valve, and a bafiie-plug arranged within the neck of the bottle at a point above said cup.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
